​

Q.  What polymer is the membrane made of?
A.  Premium ( PFAS and BPA free ) multilayer polyethylene copolymer optimized for tear and impact resistance in a hostile environment.   There is a huge variation in the polyethylene species.  Ordinary trash bag or bread bag resin will rip and have holes.  Developed with no animal testing.

​

Q.  What is the service life of the membrane ?

A.  The half life is roughly 450 years, the same as geotextile landfill liners, wire and cable.

​

Q. When the membrane degrades, will it contribute toxins to the ambient and water table ?

A.  No.  Polyethylene is simple inert hydrocarbons derived from natural gas.   There are no toxins to leach.   It has been a common practice to bury plastic for landfill liners, drainage tile, gas pipe and cable jackets.
